v0.8.2

Fixed

Comprehensive ACP spec conformance audit — aligns all method names, field names, and message structures with the ACP specification.

• session/prompt params key is "prompt" (not "content") per spec
• initialize request uses "clientCapabilities" / response uses "agentCapabilities"
• Method names use snake_case: session/set_mode, session/set_config_option, session/request_permission
• File system methods: fs/read_text_file / fs/write_text_file
• session/update notifications use nested "update" object with "sessionUpdate" discriminator
• Text updates use "sessionUpdate": "agent_message_chunk" with content block
• Permission options use "optionId" field; response is flat {"outcome": "selected", "optionId": "..."}
• Image content blocks use "mimeType" (not "mediaType")
• Plan entries use "content" / "priority" (not "id" / "title")
• Capabilities restructured to match spec (loadSession, promptCapabilities, mcp, fs, terminal)
